DC Fault Tester
HBD-81 - VA Technology Co. Ltd. (Va-Tek)
The HBD-81 DC Portable DC System Ground Fault Locator designed for DC fault testing. This equipment utilizes the principle of DC current differential detection and incorporates fast FFT (Fast Fourier Transform) technology for detailed analysis of the amplitude-frequency characteristics of the test signal. By balancing the safety and sensitivity aspects of DC ground fault locating, it effectively resolves the conflict between the two.
